6?) 1- J U) INL/ENTOR @WM WCLIM ATTGRNEKS' To all whom it may concern s i Be it known that I, BRADFORD WEBsrER, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky,have invented a new and useful Book, of which the following is a specification.

My invention relates to books or filing devices, in which leaves and other loosely attachable elements are bound on posts or guides; and the object of my invention is to provide a simpler, efficient structure in the binder and in the attachments.

The invention consists of novel features and parts and combinations of the same, which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings which are part hereof and in which similar characters of reference indicate the corresponding parts in all the views.

Figure 1 is a longitudinal elevation of the book laid flat; Fig. 2, an enlarged sectional view of the lockable post engaged by the locking slide; Fig. 3, a plan of the lockable post; Fig. 4, an elevation of the lockable post; Fig. 5, an end elevation of the binder with covers attached; Fig. 6, a perspective view of the locking slide; Fig.7, a perspective View of the loosely attachable binding spring and Fig. 8 shows the upper portion of a free post with a fragmentary sectional View of the casing bar and slide.

My invention consists of a lower base, in which are set preferably a plurality of loc able posts; of an upper casing bar, containing alocking slide, and having set therein a plurality of free pins or posts; of top and bottom covers connected respectively to said bases; of loosely attachable sheets; and of loosely attachable binding springs.

he lower base comprises a stiff bar X in Which are set the lockable posts C and C and a label-holding device W, preferably perpendicular to said base and integral therewith. The label-holding device W is preferably provided with bent edges on two opposite sides to contain a card.

The lockable posts C and C rated near their locking ends for sion of the K and K.

are perfothe admispenetrating elements of the slide more durable, and more .rarnnr orrrb n.

The casing bar A is preferably U-shaped in cross-section, the inclosed side b ing toward the outside of the book and being adapted to assist in guiding the locking slide D in its longitudinal movement. The free pins or posts B and B are set firmly in both opposite faces of the casing bar A. The inner face of the casing bar A is provided with openings adapted to admit the lockable posts C and C and to hold them against any transverse movement. The outer face of the casing bar A is also provided with corresponding openings adapted to admit the lockable posts 0 and G and to cooperate with the openings in the inner face to hold them against any transverse movement. As shown in Fig. 1, the pins or posts B and B are of such length as to stop" the casing bar A and the locking mechanism D in exact position'lengthwise of the posts so that the perforating members will find the perforations in the lockable posts accurately.

The slide D is slotted to receive the pin or post B, the edges of which opening control the longitudinal movement of the slide. One of the inside edges of this slot is provided with a resilient projection M, adapted to engage the post B resiliently and to prevent ree movement of the slide. This prevents the slide from jarring loose and thus unlocking the book.

The slide D is provided with upwardly and downwardly bent pieces L at the end to form a convenient grip for the thumb and forefinger.

I The slide D is slotted to receive and hold in position the lockable posts C and C. In the ends of these slots are set the penetrating pieces K and K, preferably pointed and integral with the slide D. hese pieces K and K are recessed so that when the posts 0 and C are pulled down into the slide as shown in Fig. 2, the slide D is locked firmly against any sliding motion.

The loosely attachable binding spring E is provided with a flat bearing surface, with a single long slot toadmit the two lockable posts 0 and C and with a leaf-spring at each end formed by bending each end of the bar inwardly. These leaf-springs extend beyond the free posts B and .B and are slotted to admit said posts. The fiat bearing surface is provided with openings for containing closely the posts B and B. The slots in theleerpeprings. eeeper ee elifl the pests H and B to prevent the spring from rock- "i do not lii'rji'i't myselftq the exact form in" which my invention is herein disclosed,
